So, last week one of my colleagues wanted to serialize an object along with custom property attribute to JSON. Interesting… JSON.NET by default will not allow serializing custom property attribute. So, you have to write custom JSON converter to fix this. Let’s take a look at how you can solve this problem

Custom JsonConverter

JsonConverter is an abstract class provides with JSON.NET that allows you to convert an object to and from JSON. By inheriting that you can customize default serialization and deserialization behavior as you want.

Reading attributes with reflection

Attributes and reflection go hand in hand. So, when you override WriteJson method to create your custom serialization, you can use the reflection to read the attributes value. When it desterilize back to the object, we can use reflection same way to set the property value.

Have you ever tried chrome inspector with Facebook? If so, I am sure you have seen this. This warning message is to help prevent Self-XSS scams.

Self-XSS

Self-XSS is a social engineering attack that is designed to gain control of your social media account. In a self-XSS attack, an attacker convinces a user to runs malicious code on the address bar of his/her web browser.

Following video covers both share-baiting (a pure social engineering attack) and self-XSS (a combination of social engineering and a browser vulnerability).

Recently we faced a problem that we need to round-up a number to greatest 10s place.
For ex: we needed to round-up a number as follows
1023 -> 2000
37911 -> 40000
912345 –> 1000000

First we checked Math.Round(). However, it did not solve our problem. Math.Round() supports only rounds a value to the nearest integer or the specified number of fractional digits. Further checking we come up a solution by using Math.Ceiling() method.

Math.Ceiling()returns the smallest integral value that is greater than or equal to the specified double-precision floating point number.
For ex:
Math.Ceiling(7.3) -> 8
Math.Ceiling(7.64) -> 8
Math.Ceiling(0.12) -> 1
